Argus Laboratory is a highly evolved molecular model software for Windows operating system. It's getting a bit out of date now but still amazingly popular. Currently, there are over 20,000 downloads to choose from. Argus Lab has a user-friendly interface, a great collection of functions, and it's a good, solid model for teaching and research.
Argus Lab was developed by a team of six scientists and one engineer who worked on the project in their spare time while attending the University of Illinois at Champaign. When they were not busy with their work, the team members worked on Arguslab full-time. Argus Lab was developed to be a powerful, open source molecular modeling and simulation software that can run on Windows, Linux, Mac OS X, and also Android platforms. This means that it can run on numerous types of computers, and it's compatible with numerous chemistry experiments.
Argus Lab was developed to make the whole process of modeling chemical processes as easy as possible, especially for beginners and students who want to do complex molecular configurations. This is because the software allows for automatic generation and adjustment of many chemical structures. For example, all you need to do is drag and drop molecular configurations into Arguslab's system, and it will automatically generate the model that you want. The design choices are fully customizable so you can have the model the way you want it.
